While the discussion pertains to Vista particularly, the same applies to Windows in general too ! For a general user the first three are usually more than sufficient to make your Vista faster. The remaining are some more which a tweak enthusiast may wish to consider. Utilities like WinPatrol or Tune-Up Utilities can help you in most of the cases.

1. Restrict the no. of start-ups. Why have programs starting up when you dont really use them. Even those you use can always be started manually by clicking on the. I personally prefer not to have ANY starups. I click on my Internet Defense Suite manually, before connecting to the Internet. So decide for yourself which one's you really need as start-ups.

2. Disable services which one may not require. For example, if your pc is a stand-alone one, there may be sevral services which you can disable or switch over to manual mode. Auto-starting and closing down of services takes time & resources. These can be saved. BlackViper's Vista Service Configurations Windows Vista Service Configurations by Black Viper is an excellent guide to follow.

3. Reducing visual effects (eye candy). Right-click on “My Computer” > Properties > Advanced > Performance-Settings > Visual Effects > Adjust for best performance > Apply > OK.
To allow the themes and the glass effects, you may have to check on the boxes : enable transperant glass and use visual styles; this way atleast the spirit of Vista will be preserved- else be prepared for a really bland Vista ! Use your discretion. I know disabling all can actually negate the purpose of 'eye-friendly' Vista.

4. Ensure that boot defragmentation is enabled, so that files used during start-up are clubbed together.
Start Regedit. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\ Microsoft\Dfrg\BootOptimizeFunction . Select Enable from the list on the right.
Right Click on it and select Modify. Change the value to Y to enable and N to disable. Reboot.

7. Generally people also recommend emptying the Prefetch directory once in a while. But Windows uses this directory to speed up launching
applications. It analyzes the files you use during startup and the applications you launch, and it creates an index to where those files and applications are located on your hard disk. Using this index, Windows can launch files and applications faster. Nevertheless clearing the Prefetcher say once a month is what I do !

8. Go to BIOS settings, by pressing del key during boot-up, and disable 'seek floppy drive' option. This saves time for those who do not use floppy drives. There are also some BIOS hacks like Enabling Quick Post, Disabling Boot Daly, etc but best to refrain from these.

9. Change Boot-Order Sequence : Normally, the bios is set to boot from floppy first, then CD and then Hard Disk. Changing the Boot-Order to be: Hard Disk first, then maybe CD/Floppy, could possibly "shave" a second, I guess !

12. Fonts take time to load. Removing some can save on resources. But one must be careful in deciding which fonts to remove. If you delete some system fonts, you may b in for trouble. Tweak VI Pro is a good shareware to manage fonts. It uninstalls fonts without physically removing them. Open its help file. It lists down the system fonts which must not be deleted ! use the list; and then decide what to delete and what to keep.

13. To REALLY reduce your shutdown time.
Start Regedit. Navigate to HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control.
Click on the "Control" Folder. Select "WaitToKillServiceTimeout"
Right click on it and select Modify. the default value is ( i think) 12000.
Setting it to a lower 4 digit value,( say 1000) will make your PC shutdown faster, but you could end up losing data, so use this tweak judiciously.

14. Get rid of all the extra programs Windows Vista installs. You may not be using some like WLM, Calculator, Games, Meeting Space, Fax, etc. Go To Control Panel\Programs\Programs and Features > Turn windows On or Off and do the needful.

15. Go To Control Panel\System and Maintenance\Performance Information and Tools. On the LHS you will see options to Adjust Indexing options, visual effexts, power Settings, etc. These all help directly and indirectly.

Do remember that your Vista-based machine will tend to run a little faster, after the first few weeks after it's installed, thanks to its new feature called "SuperFetch"Windows Vista: Features Explained: SuperFetch ; which basically studies the programs that the user frequently runs and loads them into memory automatically.

If You want to upgrade Your computer performance. You first Have to decide on
What you are going be using the computer for. If you are going to use it for Examples: education, Home use, you should first upgrade your computer for a newer processor Such as intel dual core, then you are going to upgrade your memory. If you have 265mb, 526mb 1000mb (1GB) you should need at least need 1GB for Minimum performance. But, if you are going to use it for gaming you need 2GB AT LEAST, and you need a good graphic card and also 120gb hard drive at least. And then after you choose you edition of vista you have to get a good brand. TOSHIBA, acer and Compaq(HP) are the leading companies. Once you get a good brand you should also get a good warranty [ONLY FROM THE COMPANY] but not retail store especially if you are getting a laptop.
